ER Diagram Feature (#1588)

I know this is a long shot... In an ER Diagram - when creating a n:m relationship between two entities, would it be possible to provide a button or other mechanism to convert the relation to a link table? E.g. adding a "Person" and "Role" entity, then setting up an n:m relationship between them, will convert the n:m relation to a "PersonRole" table with two 1:n relationships between the "Person" and "Role" tables. It would greatly simplify database creation if possible.
